Fleet Aircraft Service Squadron

Fleet Aircraft Service Squadrons (FASS) were specialized support units within the United States Navy, established during World War II to provide maintenance and logistical support to carrier-based aircraft. These squadrons were responsible for the repair, servicing, and supply of aircraft aboard fleet carriers and at forward operating bases, ensuring combat readiness during intense naval operations in the Pacific Theater. FASS units played a crucial role in maximizing sortie rates and minimizing downtime for both fighters and bombers, contributing significantly to the Navy's air superiority. Their efforts enabled carrier air groups to sustain prolonged operations during critical campaigns such as the battles of the Philippine Sea and Leyte Gulf.
